Hi.. I have a bathroom that will be remodeled.. House is 50 years
old.. Bathroom has plaster walls.. The current tile goes up about 5
feet high.. Then from there to the ceiling its plaster....

Some people say we should demo the entire wall...Even the part where
the tile stops... Completely remove all plaster walls to studs...

Other people say, you can save money... Just demo the tile..... Where
the plaster goes to the ceiling, just feather it with sheetrock and
you wont be able to tell the difference... What do you think? I'm
thinking its better to demo all the walls to the studs... any advice
